i don't have 6ft distance from the center sadly, i should try reducing the actual distance of the speaker, also how should the headphone graph be like? the two tests have a very different graph and i don't know in which case it should be better @musicreo can you tell me how i can read the graph? for me the test1 seems better than the test2, am i right?
For me both graphs look similar. There is no obvious problem with the graphs and everything looks ok. The difference between the channels is also not bad. If you wonder why EQ-APO shows you a different graph that is because that graph is the sum of left or right channels. . Which speaker do you use? They seem to have a lot of energy in the low frequencies as the range between 35-60 Hz is boosted a lot.
I'd like to help, but I don't have knowledge of acoustic science or the technical aspects of Impulcifer or HeSuVI/EQ-APO to suggest specific fixes. I can only describe what I did and what I hear. I only did stereo measurements of my speakers with the binaural mics in my ears, and room measurements with a UMIK-1 positioned at the location of each ear. My speakers were about 7 ft in front of me and about 7 ft apart, so the traditional triangle. I also only use the "Stereo" settings in HeSuVi. But the imaging and soundstage I hear with Impulcifer is what's in the recordings. Some literally fill half the room in front of me, nearly 180 degrees wide, others are just the individual instruments as they would be realistically positioned. Width, height and depth vary greatly, depending on the recording. I understand that stereo recordings can be played back using a multi-channel simulation, which may be what you're after to expand the soundstage wider than what's in the recording. But if you want the imaging to be more true to what's in the recordings I think the answer is in how the measurements are done and the positioning of the speakers. I'm sure others can offer more precise technical options, but just wanted to offer my experience.
To be honest I tried those sliders and to my ears I couldn’t hear the difference. But the recording I got now makes it feel surround around the walls of my room. Even the rear speakers feel a distance away. As @lowdown said it’s all down to the stuff that you’re listening to. Some sound far and wide, some things closer especially in movies… 1917, avatar sounds amazing with distinct sounds in many directions, other movies sound closer like Dolby preset in hesuvi.@morgin i read that times ago you asked how to have the stereo audio more "large", i too found that 7.1 when plays stuff in stereo is too much centered even with the hesuvi front slider, doesn't help much... this is why i use ofter 5.1 instead of 7.1 with FL and FR settings more "large"
this is the only way i found to enjoy the content in stereo without having that tunnel like sound coming only from the front speakers
if there was a way to set the volume of each channel for the upmix content in stereo, would be great, i'd like having the sound coming from all the channels but mostly from the front...
Definitely try sitting closer to the speaker. The further you are, the higher is the reverb level going to be relative to the direct sound. This is different from decay time and cannot be controlled in Impulcifer but is easy to do with distance to the speaker.
My graph is with room correction up to 750Hz and you can't compare it with your graph up to that frequency. The spikes in this frequency regime are room modes and will vary a lot depending on your position in the room.
Like jaakkopasanen suggested decrease the distance to your speaker. When you sit close to a wall you will have reflections from that wall that will be hard to separate from the direct soundwave.
I remembered wrong. The target level doesn't set the peak but the average level and therefore negative values should be used. The purpose of this parameter is to ensure different measurements are equally loud for more fair comparison.
Can only suggest freely experimenting. Did you try using some of the balance command line options to help with that "sound being mostly from the left"? I've seen some posters say they got the measurements so close between L and R that they didn't need balance options, but I tried many combinations and got my balance perfected with command options rather than more measurement or speaker adjustments. There are obviously many variables and I think it just takes trial and error to get great results.
Morgin, how do you play the film : vlc, mpc-hc.. ? Are they mkv file in 7.1 ? What is the audio configuration of the player (outputing 7.1 channels ?) , of windows playback device and of Hesivu whan you play the film ?
